[Steven Rostedt]

3.6.11.2 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Mugunthan V N <mugunthanvnm@xxxxxx>

[ Upstream commit 7e51cde276ca820d526c6c21cf8147df595a36bf ]

To restart tx queue use netif_wake_queue() intead of netif_start_queue()
so that net schedule will restart transmission immediately which will
increase network performance while doing huge data transfers.
